I like the KG figure, but to be honest, I'm not a big fan of the neck poses. I'm sure people will automatically rate this as the "best Ghidorah figure ever!" simply because it's an Xplus, but at $300 (remember back when these could be pre-ordered for $100-$150?), I still think the Gigabrain KG figure is
the showa Ghidorah figure to beat. If I find this at a store for $200 or under, I would definitely consider it, but otherwise, nope, I'm staying retired from collecting.
In regards to the Mosu-Goji figure, that's one ugly, distracting face seam for a figure costing over $400+:

Easy pass....staying retired.
